COM (Serial) Ports

COM 3 to COM 6 are ﬁ xed at RS232.

The pin function of COM 1 and COM 2 ports will vary according to JP1/JP2’s set-

ting. Refer to “COM1/COM2 RS232/RS422/RS485 Select” in this chapter for more

The serial ports are asynchronous communication ports with 16C550A-compatible

UARTs that can be used with modems, serial printers, remote display terminals,

and other serial devices.

Connecting External Serial Ports

Your COM port may come mounted on a card-edge bracket. Install the card-edge

bracket to an available slot at the rear of the system chassis then insert the se-

rial port cable to the COM connector. Make sure the colored stripe on the ribbon

cable is aligned with pin 1 of the COM connector.
